No, I mean 24. As a Carroll fan I can appreciate 42, but that's
nothing compare to 24.
... and the 24th root of unity !

Take an incomplete theory T. Suppose that -p is not provable in
the theory, then you can add p, as new axiom, without being able 
to prove -p. This means p
is consistent with the theory. In particular the theory T+p is
a consistent extension of the theory T. Now a consistent computational
extension is a consistent extension where p is DU-accessible.
p is generated by a computation. It will be translated (in arithmetic)
by -Bew(-p) with p sigma_1.

I'm afraid you have hallucination. What kind of pot are you smoking?
I don't see any "1st person" occurence used as  a mind-like
hidden variables.

Do you agree there is no bigger prime number ? If you agree it means
you can understand what I mean by the existence of a number and by the
non existence of a number. "other" form of existence will appear in
the talk of some machines ...

OK jacques, you got the point. From now on I will say that there is
an objective measure distribution. It is no more relative than the
square of the PSI function apply to an Everett Relative State.
And after all, that is what I am getting to.

I was using yours!

I do distinguish persons by their memories, when they have distinguishable

Perhaps we are immortals for more than one reason.

With this definition, well, the problem is quite open ...

I don't know.

I agree essentially.
